PURPOSE:To lessen the number of components of a suction grille as a whole and to enable rational execution of a operation by providing a catch in the upper part of the rear of the suction grille and by equipping the catch with projections serving as stoppers between the catch and the main body of an air-conditioner. CONSTITUTION:A suction grille 3 is long in the lateral direction and metal fittings 18 and 19 are fitted vertically by fitting screws 20 for preventing a warp and the like. The lower metal fitting 19 has a structure of supporting an air-filter 17. To the rear of the upper part of the suction grille 3, stoppers 21 and 22 for fixing the suction grille and for positioning it are fitted on the right and left sides and in the center, by one, respectively. When the suction grille 3 is drawn, it moves in the direction A of the stoppers around the lower part thereof and stops. The stopper 22 fitted in the center of the suction grille 3 operates so that the suction grille 3 moves in the direction of an arrow C on the occasion of replacement of the air-filter 7. By the combination of a recessed part 23 of the stopper 22 with a hole 24 of an intermediate plate 14, the suction grille 3 is made to move around th lower part and stopped, and thus the replacement of the air-filter 17 is performed. |
